, This invention relates tofheel assembling machines oi the type in u'liichj'tivo or more lifts or heelV sections maybe assembled to'4 form alheel unit which may bev itselfeither .i-f, a. complete heeloran assembled section to be combined with. still vanotherfheel part. As exemplified hereinthe\n iachine Ymay be arrangedtofacilitate theiass'embly of a` heel base and a rubber heel to form acomplete 3; lieel unit ready for attachmenttoashoe.

An objectv oi" the invention is to. produce an` improved heelA assemblingmachine which shallnot only becapable oi easyand rapidv operation but shall be vprovided with such adjustments that it,l can be quickly adapted to operateupoii heel sections of anysize and,` While insuring accurate register ofthe assembled heel` sections, can` be changed from'one size to another inl a minimum amount or" time ff.: and with a, minimum eigene-rt, whereby increased production 1n ay befsecuredat less eX.-

pense formachinery, labor andiactory space than has heretofore been necessary;4 With the above Ystated object in vieyv "an important feature lof vthe invention consists in a double-deck heel holder comprising normally innnovable side gagesior positioning transversely one section of a heeland' yield-v inggages mounted upon said adjustable gages for positioning `transversely. another section osaid heel.V rl'lie first-named gagesareprefy erably adjustable to the size ofonefheel secf tion to. be dealt with, Whilethe-yieldinggages which position, the other heel,- .section relatively to the iirst permitfthe seoondfsection to be' inserted easily andqui'clly and insuref that itshall be registered properly.y with the first.l In the illustrated'machine the unyieldingside gages are combined Withbreastgages V i which. partake of the adjustmeirt-V of the side gages and provide for positioning a heelsection longitudinally as Well astransversely'.

ln another aspect the invention provides a double-deck. heel holder comprising separate gages Jfor the breast portions oiQtWosuperpOsedsections of; a lieel separate gages for the rear portions of said sections, and means .for simultaneously adjusting the breast and the rearv gages towardV or .from

Y eachother longitudinally` oi theheel. As

shown, one of the rear gages maybeunyieldchine toraccommodate heel sections of dif-4 ieren-t sizes consists' in the provisionof `an ex'pansible and' contractile pressure 'applying pad,l combinedv with Vmeans for adjustingtlie size of the pad to conform to diiierent heels. By thisineans the usual necessity for providing a series oi interchangeable pressure applying' pads of diderent sizes'isseliminated andthe timerequired to change the machine t is materially reduced." 'In the illustra-ted em,- bodiment of the invention thepressure applying pad comprises a series of radially rela-1 Vtively movable pressing sections, and means Vis Vprovided for adJusting said sections ra-` dially to varythesize of the pad. Preferably single adjusting means is employedyfor,

this purpose and. this may advantageously' consist of a Wedge element operated", for eX- ample,1by a screw and arranged toengage and" mo'veiall of' the radially movable sections.

Theabove and other'features ofthe in- K1 vention, as Well as the advantages derived from their use, Will beV better understood and appreciated fromrealding the following de# tailed description of' one good practical einbodiment ofthe `invention,` in connection with the accompanying drawings, in whichV Fig. l is a View in side elevation, partly in Vcentra-l, longitudinal'section, ofV a" heel assembling machine embodying the invention.;` l I l l 2 is a plan View ofthe'blank` assern# bling portion of the machine, showing the double-deck heel holder; y y l Fig. 3 is ay section of partfof the lieel' holder, taken on the line III-IIT of I `i 3j.h2j; F ig. 4L is a front elevation of the pressure applying pad? f Y Fig. 5 is an underside `pla-n view of the pad with parts broken away; e

Fig. `6 isa-planr view ofthe heel 'holder with parts/brokenk away to show details of the adjustmentgand Fig. 7 is a front elevation of the heel holder.

Referring now to Figs. 1 and 2, 10 indicates the base and 12 the pressure pad carrying arm of a heel building machine of a well-known type.

The double-deck heel holder of the present invention is mounted upon a table 14 which is secured to the base 10 by bolts 16. The holder comprises a work receiving plate 18 in which are provided guideways 2O for a rear gage 22 which is normally immovable, but is adjustable longitudinally of the heel holder.

The rear gage 22 is adapted to engage and position one section 24 of a two-section heel of which the second section is shown at 26. As illustrated, the heel sections 24 and 26 consist respectively of a rubber heel and a heel base which it is desired to secure together to constitute a complete heel ready for attachment to a shoe.

Yieldingly mounted upon the rear gage 22 is a second rear gage 28 which is slidab'ly mounted upon said gage 22 and yieldingly pressed toward the front of the holder by a compression spring 80, the front end of which bears against a pin 32 screwed into the member 28 (see Figs. 1 and 3). It will be apparent that the gage 28 will partake of any movement of adjustment of the member 22 but will be capable at all times of yielding relatively thereto, and the dimensions of the parts are such that the gage 28 will engage and position the second heel section 26. Fore and aft adjustment of the above-described rear gages7 longitudinally olil the heel holder, is eiiected by one of the two sets of threads of a right and left screw 34, the rear endoi` which is swiveled in the stationary table 14, as shown at 36, in such a manner as to prevent longitudinal movement of the screw, while permitting it to be turned freely about its axis. he right-hand threads 38 of the screw engage corresponding threads in a lug 40 (see Fig. 3) depending from the rear gage 22, through which lug the screw 34 passes.

The left-hand threads 42 of the screw 34 engage corresponding threads in a. lug 44 depending from a slide 46 which is also guided for fore and aft longitudinal movement upon the table 14. rlhe adjusting screw 34 is provided with a knob 48 by which` it may be turned in one direction or the other to adjust the rear gages 22, 28 and the slide 46 simultaneously toward or from each other.

Supported upon the slide 46, and movable therewith, is the breast and side gage mechanism which will now be described. Slides 50, 52 (see Figs. 2 and 6) are supported and guided for transverse movement upon the member 46 and are simultaneously adjusted toward or from each other, transversely of the heel holder, by a right and left screw 54 provided with a manually operable knob 56. Upon each of the slides and 52 there is formed a breast gage 58 and a side gage 60, which are properly disposed to be engaged by, and to position, the breast and side edges of the heel section 24.

From the foregoing it will be apparent that rotation of the knob 48 will eiiect adjustment or' the breast gages 58 and the rear gage 22 toward or from each other, the side gages 60 moving with the breast gages 58 and the yielding rear gage 28 moving with the rear gage 22. Y Independently of this adjustment rotation of the knob 56 will eliiect transverse adjustment to the side gages 60 toward or from each other so that the holder may,'by manipulation of the knobs 48 and 56, be adjusted accurately to fit and position the heel section 24.

For positioning the superposed heel section 26 in proper register with the iirst section 24 there are provided additional breast gages 62 which are carried by the slides 50, and are guided to move reely through said slides longitudinally of the heel holder. The

outer ends ot' the gages 62 are turned down-l ward, as shown at 64 (Fig. and engagein a groove 66 in a transverse adjusting plate 68 operated by screw 70 threaded into the slide 46. rlhe screw 70 has a manually operable knob 72 and a disk 74 (3o-operating with a groove 76 in the under side oi' the;

plate 68 to effect the adjustment. Pins 78 secured in the slide 46 co-operate with diagonal slotsY 80 in the plates 68 so to guide the plate that it moves longitudinally of the heel holder when the adjusting screw 70 is operated, thus causing the breast gages 62 to be adjusted longitudinally of the holder relatively to the gages 58, this adjustment not being affected in any way by transverse adjustment of said gages because the groove 66 is parallel to the adjusting screw 54. The purpose of adjusting the gages 62 relatively to the gages 58 is to provide for positioning the heel sections 24, 26 either with their breast faces in alinement with each other or with one overhanging the other, as may be required by the nature of the work in hand.

For the transverse positioning of the upper heel section 26 there are provided side gages 82 which are pivoted at 84 upon the respective slides 50 and 52, and have at their outer ends blocks 86 (see Fig. 3) which engage l'reely in a transverse slot 88 formed in thetop oi a `shaped member 90 which is guided for longitudinal movement in guideways 92 formed in the slide member 46. A pull spring 94 tends continually to draw the member toward 'the front of the machine and thus yieldingly to close the side gages 82 inward toward each other. 4Since the slot 88 is also parallel to the screw 54, this operation is unalected by any change in adjustment of said screw, the: angulaNeX/ten't; voii-"the closing movement of the :gagesf82'about their piv-` ots 84' being determined vsolely by au adjustable stop screw? 96" threaded inthe slide :46 and against the po'intvfewhioh screw the memberltQO iinpinges. l From the ereg'oingit willbe `clear that, t'he proper adjustments having'been made toA provide forthe siZi-is-and 'shapes1 of the heel sections to be assembled ,'one"section,` Vas a rubber Vheel 24, 'may' Abe 'placed in position between thegages22,58, 6 0'- and then va secondrsectionf'asA alhfeel base 26, may be inserted between the *yielding/side:gages AS2 with its breast facelagainst the breast gages 62, the rear l 'gage 28-yielding? topermit the heel base to be lpressed;icl-own into fengagef ment withV the rubberheel land insiiring- 'that the said base fwillbe positioned accurately against the breast gage62, inaccurate register with the rubber heel.

Y `Crdlinarilfy the heel sections to be asernbled will `have been previously coated with ycement andall that isl necessary to secureA them-to-A gether after they are properly registered with' each other is'the/application of pressure. For this purpose there is provided the improv-ed pressure applying pad which lforms a part of the present inventionand which will now be described. Supported in the :arm 12 is a vertical plunger 10d-which is screw-*'threadedfas 'shown at -102 and arranged' for vertical adj ustment by means oan linternally'threaded rotatable sleeve 104 having at its lower end a flan-ge'lOG uponwhich bearsa heavyl spring 108 the tension ot-which-is adjustable by means ofla sleeve 110 threaded into the arm 12; The-spring IOSis so stii' that-'it will yield only when such excessive pressure is exerted as to endanger the "machine To the lower end of theplunger 100 lisV secured a head 112 having initsundersi'de'farcuate guideways for' `an v"intermediate supporting member 114/ which is`-`held up to thehead 112 by boltsv 116` surrounded by springs 118 and'movable to `a limitedy extentin slots to' permit theV pressure pad to adjust itself angularly to thewedge'of Ethe heel.

The pressure applying pad itself comprises a base block 122 which is bodily adjustable forwardly and rearwardly of the intermediatemember 114 by means of an adjusting screw 124. The under side of the block is provided with radial guides 126 in which acre supported a plurality of radially movable pressure applying sections 128 (see Figs. 1 and 5). The general outline of the sections collectively is that of a heel and by Vmoving the said sections radially inward or outward the size of the presser pad may be adjusted to conform to the size of the work to be dealt with. l j

interposed between the respective sections 128 and retaining plates 130, .Which are secured-to the base bloclr122 .by screws 132, are compression springs 134-whichjtendt0 contract` the pressure applying pad `by' moving all the sections thereof radially inward. Theinnorportions` of the sections'128 are beveled o'r incline'd,'1asv shown at 13G, and are engaged by a wedgeimember 138. ati the lower end o1n averticalscrew 140 surrounded by -a rotatable but vertically immovable nut 142`having in lits periphery teeth 144 which are engaged Vby an adjusting screw 146, at the outer end-ot` which isra manuallyV operable knob 148 by the rotation ofl which expansion Vor contractioinfand consequent adjustmentiinasize, of the pressure applying pad-may be effected? to cau'seit to contorni tothe size tofwhich the heel holder has been adjusted. f a, Y mi `This 'last described v adjustment lhaving been'made the arm12 is drawn forward tort-he position shown in Fig. l1, whereupon it is automatically caused to-descend fby mechanism'well-knownfin machineslof this .type andto applyrthe'desired attaching pressure to thel vheel sections which have been-assem- Vbled/inthewholder. j t
